So if you’re probably wondering what e-liquid is all about! What does it contain? Is it safe to use? Are there any side effects? And maybe you have many other thoughts that pass through your mind in order to clarify any justification before you decide to start using an electronic cigarette device.
Here we will aim to outline any queries and concerns you may have regarding the usage.
So let us first start with the name E-Liquid, which is a term used to signify that the liquid content is to be used in conjunction with an appropriate electronic cigarette device, hence the first letter being ‘E’ . There are some other terms used instead of e-liquid, some of which are e-juice and smoke-juice.
So what does E-liquid contain?
Flavours and nicotine are dissolved in hygroscopic (absorbs water from the air) components, which turn the water in the solution into a smoke-like vapour when heated. Commonly used hygroscopic components include propylene glycol, vegetable glycerine, andpolyethylene glycol 400 (often sold under the abbreviations PG, VG, and PEG 400, respectively).
Safety of liquid bases
All three liquid bases are common food additives used in a variety of pharmaceutical formulations. Propylene glycol, the current dominating liquid base, has been utilised in asthma inhalers and nebulizers since the 1950s, and because of its water-retaining properties, is the compound of choice for delivering atomized medication. The U.S. Food and Drug Administration (FDA) includes propylene glycol on its list of substances Generally Recognized as Safe (GRAS), and it meets the requirements of acceptable compounds within Title 21 of the Code of Federal Regulations.
The main prominent base fluid of e-liquid tends to be Propylene Glycol (PG) or it can also be Vegetable Glycerine (VG). Contents of the e-liquid solutions vary, but their common aspects include water and flavourings in a propylene glycol or glycerine base.Nicotine is also included in solutions intended to fulfil a nicotine replacement role. PG or VG liquid is used as the carrier to provide the nicotine to the user; however users also can use electronic cigarettes with zero nicotine content e-liquid. The base fluids produce the smoke simulations visible when used with an appropriate electronic cigarette device.
Hundreds of different flavour varieties are available, such as regular tobacco and menthol. A wide variety of food flavours are also sold, from the traditional (vanilla, coffee, cigar) to the more exotic (strawberry, watermelon, mango), some flavours aim to mimic specific cigarette brands, such as Marlboro or Camel. All flavours are subjective, and each person will have a subjective experience of the taste. Generally tobacco flavours or those that aim to mimic tobacco brands are still a stretch away from having the same flavour as a traditional tobacco cigarette brand, but still effectively offer the user a similar flavour that as well as being reasonably compatible, also offers the simulation of a great throat hit, and plumes of vapour plumes whilst simultaneously delivering the desired nicotine to the user.
Liquid solutions containing nicotine are available in differing nicotine concentrations to suit user preference. Dosing nomenclatures are not standardised and vary by manufacturer, but tend towards the following rough figures
• Liquids said to contain "low" doses of nicotine tend to correspond to a nicotine concentration of 6–8 mg/ml (milligrams of nicotine per millilitre of liquid).
• "Midrange" or "medium" doses tend to correspond to a nicotine concentration of 10–14 mg/ml.
• "High" doses tend to correspond to a nicotine concentration of 16–18 mg/ml.
• "Extra-high" doses tend to correspond to a nicotine concentration of 24–36 mg/ml.
Actual numerical nicotine concentration ratings are usually printed on liquid containers or cartridge packaging. Often, the standard notation "mg/ml" is shortened to a simple "mg".
the higher the nicotine content, the stronger the throat hit, which is the
sensation the user experiences at the back of the throat upon inhalation from
their electronic cigarette device.
